5G Core Network Function Segmentation for Registration Efficiency

The patent segments the 5G core network into distinct functional units: Access and Mobility Management Function (AMF) for registration management, Session Management Function (SMF) for connection management, and User Plane Function (UPF) for data transmission. This segmentation allows each function to be independently optimized and managed, improving overall service delivery quality while maintaining manageable complexity through modular architecture.

The patent implements network slicing capabilities that allow a single 5G core network infrastructure to serve multiple diverse access networks simultaneously. The AMF, SMF, and UPF functions are designed to handle various access types (3GPP and non-3GPP) through universal interfaces and protocols, enabling one system to perform multiple functions across different network environments without proportionally increasing complexity.

The patent implements self-service mechanisms in the registration process where the AMF automatically manages mobility management contexts, connection management states, and service authorization without requiring manual intervention. The system autonomously handles registration requests, maintains state information, and coordinates with other network functions, improving registration efficiency while keeping complexity managed through automated processes.
